Electronic photorela for street lighting is intended to optimize the consumption of electrical energy. With the onset of twilight, the lighting turns on and regulates the intensity without human participation. At dawn - automatically with a potentiometer, the fading mode is turned on to a complete shutdown.

When illuminating large areas, such as - car parks, warehouse bases, garage cooperatives, etc. Not rare such photorels are used for road and street lighting. The use of photorel brings significant energy savings and respectively reduces utility fees. The device has a range of settings modes. In everyday life, it will be useful to summer houses and household owners.
Principles of work of street photorele
The triggering of photorele's contacts occurs at the time of entering the sunlight or with the onset of darkness.
- Sensors that react to light are located on the housing or exile, depending on the type of photoyele. Two time modes are provided in the photorele program: Winter - Summer. Thus, you can adjust the inclusion and shutdown of light depending on the time of year.
- Such a device is quite economical and benefits when installing not only in the entrance for night lighting or industrial zones, the photorelay has the ability to synchronize with the irrigation system and watering. An additional device will allow you to regulate watering at the earlier time and after sunset without your participation.
- Progressive systems programmed to save energy resources are included in the housing equipment program called "Smart Home". Such a snap-in home imitates the presence of the owners in the residential premises and performs their home care functions during their absence or rest. Network equipment LED light bulbs significantly reduces electricity consumption.
- When choosing and acquiring photorel lighting, pay attention to the degree of sensitivity sensitivity. The higher the sensitivity, the more expensive and saving the device of the photoyeler. It is advisable to purchase a photoyeler with a smooth regulator of a shutdown threshold and a built-in timer.
Specifications of photoyela for lighting
When choosing a photoering drawn attention to the maximum permissible loads. Depending on the number of connected devices, the maximum permitted loads range from 1000 to 2300 W, depending on the type and model of the instrument.
- Some models of photoele are equipped with a photocell inside the housing. Other models are equipped with a timer and a trigger threshold regulator. Some models have remote photocell sensors. The choice of model and equipment depends on the specifics of the operation of the instrument and the installation conditions.
- The device is designed for the nominal working voltage from the household network 220 W, and the lubrication of the relay sensors from 2 to 2000 (LC) suites.
- Choosing a photoyeler, keep in mind that the reliable degree of IP44 protection allows you to use an open-air device. The hermetic case is opposed to any weather whims. In additions with such a threshold of protection, the degree of triggering of the sensors 5 - 50 LCs, and the allowable temperature differences - from 25 ° C to + 40 ° C.
It is worth remembering that in the saturation of light in 5 lk, darkness occurs, but the outlines of objects are still distinguishable to the human eye. During saturation in 2 LCs, deep twilight occurs.
Photowel Connection Scheme for Street Lighting
In the photorela for street lighting, the diagram provides power from a regular network of 220 volts of alternating current and switching voltage in the chain to 10 amps.
On the attached scheme of street photoorele, it can be seen that an indicator photodiode operating on the principle of the photo cell (HL-1), resistance (R1 and R2), is used at the sensor site (HL-1), resistance (R1 and R2) controls the sensitivity functions of the photoering.
Connection options for outdoor lighting
On the instrument itself and in the applied instruction manual there is a diagram of connecting a photoyeler to the network of outdoor lighting. For the installation of photorele, the electrician services are not needed. Connect the photogele is not difficult. It is only required to connect in accordance with the scheme.
- For easy installation and connection, the device is equipped with wiring releases with different color insulation. Standard colors for household appliances is usually this: black - phase, red insulation - switching phase, and blue or green color - zero.
- Connection of the photoering is made in the distribution box area. On the wall it is fixed on the mounting screws of the photowork box, and the mounting wires are output. When installing the box, caution is required to not damage the wires hidden under the stucco.
- The load switching is carried out by interrupting the phase voltage and its shutdown. The zero wire connected to the blue or green wire is necessary for the power supply, the working voltage of the photowork is up to 230 V. The mounted device has a nominal limit load capacity of 10 A (2.2 kW).
- In case the switching load has an increased power, more sensitive switches are used to control the instrument.
